SAW-GUARD.

SPECIFICATION forming part of Letters Patent No. 284,849, dated September 11, 1883.

Application filed February 6, 1883. (ModeL) To all whom it may concern Be it known that I, LEONHARD HOFMANN, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Guard for Circular Saws, of which the following is a full, clear, and exact description.

My invention consists of a hood or case to cover the saw, so as to guard the operator from harm in case of falling or swinging his hands towardthe saw, the said guard or shield being mounted on a support by which it can be supported in a manner that avoids interference with the work, and so that it can be shifted higher or lower to suit different kinds of work,

and the support for thesaid guard being detachable for removal when the saw is to be used for grooving stuff by passing the same over the saw, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a saw-table with my improved guide attached. Fig. 2 is a sectional elevation of the same, and Fig. 3 is a perspective View of the support for the guard.

The guard consists of a hood or case, a, of suitable form to cover the upper portion of the saw projecting upward from the table I). It is to be made of thin sheet metal or wood, as may be preferred, and provided with arms 0 for connecting it to a supporting-standard, d, by a clamp-bolt, e, said arms to be extended from it in such direction and to such extent that said standard may be located at such place on the table that it will not prevent the boards to be sawed from being suitably presented thereto. The standard is to be detachably connected to the table by passing through a slot in it and receiving a key, f, passing through it below the table and drawing the shoulders g firmly downon the table or block 45. I prefer to have the tenon h of the support to pass through the block below the table-top for greater steadiness of the support. The clampbolt 6 passes through a slot, in the support d, enabling it to be shifted up and down to set the guard higher or lower; and for preventing the guard from falling on the support, the latter is notched along one edge, It, and the lower edge, Z, of the guard is contrived to spring into said notches for re-enforcing the clamping-bolt.

Vhen itis desired to lower the guard on the support d, the edge Z may be pressed out of the notches by the hand after loosening the bolt 6, when the guard may be adj usted higher or lower, and secured as before,-and while the saw is running, if desired.

The slot at in the table represents the place where the saw is to be located.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a saw-guard support, the standard d, having the slot 9', teeth 70, shoulders g g, and key-hole in tenon h, in combination with the table I), the key f, the apertured block 5, the bolt 0, with its clamp-nut, and the guard-arms c 0, as shown and described.

2. The guard for a circular saw, consisting of a case or hood, a, provided with arms 0,

' and being fastened to a slotted support, (2, by a clamp-bolt, 6, said support having notches k, and the guard constructed to rest by its edge Z in said notches, substantially as described.

LEONHARD HOFMANN.
